Comparative Analysis of One Health Policies in Asia for Exploring Opportunities for British Columbia in Canada.

In response to emerging challenges that intersect humans, animals, and environments, there is growing international exigent need to adopt 'One Health' approaches. While One Health efforts are emerging in British Columbia in Canada, there are still challenges to overcome in the adoption of a One Health approach in policymaking. We conducted a comparative analysis of One Health policies in Asia, specifically, Singapore, Hong Kong, Bangladesh, and Thailand, which have well-established and sophisticated One Health approaches, to determine good practices in the implementation of One Health that could be considered for adoption in British Columbia.

Role of CTLA-4, IL-18 and IL-10 on the Induction of Low Dose Oral Tolerance.

Oral Tolerance is the temporary loss of systemic immunological responsiveness to a specific soluble antigen after ingestion of that antigen. Results from our lab and others indicated that CTLA-4 and lack of IL-12 played a role in the induction of low dose oral tolerance at the Th1 cell level. Previous literature suggested that IL-18 also played a role in preventing oral tolerance induction while the cytokine IL-10 had been shown to be a factor contributing to suppressed immune responses.
